A Mi?! W/TI'VESSES A 770/?NEYS HUNETE WILLIAM S. EMERY, OF NEW YORK, N. Y.

POST-HINGE.

I To all whom it may concern:

Be it'known that 1, WILLIAM S. EMERY, a

,citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New .York, have invented a new and Improved f Post-Hinge, of which the'following is a full,

clear, and exact description.

The invention relates to post hlnges for water closet seats, covers and like articles, such as shown and described in the Letters Patent of the United States, Serial No. 900,514 granted to George A. Geary, on October 6, 1908.

The object of the invention is to provide certain new and useful improvements 111 post hlnges of the character referred to,

whereby the spring pressure is graduated and a stop is provided for limiting the upward swinging motion of the seat, cover or like article.

The invention consists of novel features and parts and combinations of the same,

which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented 1n the accompanying drawings forming a part of this specification, in

which similar characters of reference indicate corresponding parts in all the views.

' Figu'rel is a sectional side elevation of I Fig. '3

the improvement, showing the seat, cover or like article in raised posltion; Fig. 2 is an enlarged sectional side elevation of the alike view of another form of the stop.

The tubular post A of the post hinge is 1 provided at its under side with a bolt B passing through a fixed support C and having its nut screwing against the under side of the support C. The upper end of the tubular post A is closed by a screw cap E, and the. said post A is provided with diametricallyflrranged and vertically-disposed slots A, through which extends a crank shaft F,-having its outer ends rigidly connected with an arm G, screwed or otherwise fastened to the seat or cover H. The crank arm F ofvthecrank shaft F extends within the postA and engages the forked end of Specification of Letters Patent.

Application filed September 25, 1908.

Patented May 25, 1909.

Serial No. 1=54l,6'79.

an extension I of a washer I, pressed on by one end of a main coil spring J, arranged within the post. A and abutting with its other end against the under side of the screw cap E. By screwing the screw cap E farther in or out the tension of the main coil spring J may be regulated to suit existing conditions.

In order to relieve the main coil spring J of undue tension when swinging the cover, seat or like article H down into a horizontal position, use is made of auxiliary coil springs J, J of which the spring J is arranged within the central opening of the spring J and is of less length and strength than the main spring J. Thus when the cover H is in an uppermost position, the upper end of the spring J is a distance from the under side of the cap E and only comes into action shortly after the article H has begun to swing downward toward the horizontal position. The spring J 2 is arranged within the opening of the spring J, and is of less length and strength than the spring J, so that this spring J 2 does not come into action until the article H moves to its final horizontal position, as will be readily understood by reference to Fig. 2, which shows the three springs J, J and J 2 compressed. Thus by the arrangement described, a graduated spring pressure is provided for the crank shaft F, it being understood that when the cover H is in an uppermost position it requires less pressure to hold it there than when the article is swung into a horizontal position.

In order to limit the upward swinging motion of the cover, seat or like article H, various means may be employed; for instance, as shown in Figs. 1 and 2, the crank shaft F is provided with an integral stop lug K, adapted to engage the under side of the washer I, as soon as the cover, seat or like article H reaches its uppermost position. Now as the stop lug K abuts against the spring-pressed washer I, it is evident that a yielding stop is provided.

As illustrated in Fig. l, a stop lug E is formed on the top of the screw cap E, to be engaged by the arm G, at the time the cover, seat or like article H swings into an uppermost position; otherwise, the post hinge is the same as above described and shown in Figs. 1, 2 and 3.

In the modified form illustrated in Fig. 5,

a stop pin E is provided on one or both sides of the screw cap E for engagement by the arm G, at the time the article H reaches an uppermost position.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:

1. A hinge of the class described, comprising a tubular post, a shaft mounted to turn and to slide in the post and having an arm for the purpose set forth, a Washer engaging the shaft, a spring between the washer and the top of the post, and a lug on the shaft for engaging the washer and the post to limit the movement of the arm.

A post-hinge for Water-closet covers, seats and like articles, comprising a tubular post, a crank-shaft mounted to turn and to slide in the said tubular post and having a stop lug and an arm for attachment to the cover, seat or like article, a washer engaging I the crank-arm of the said shaft and adapted to be engaged by the said stop lug, and a spring within the tubular post and pressing the said washer.

A hinge of the class described, comprising a tubular post, a crank arm mounted to turn and to slide in the post and having an arm for the purpose set forth, a washer on the crank arm, a plurality of springs of different lengths arranged between the Washer and the top of the post, and a stop lug on the crank arm for engaging the washer for the purpose set forth.

in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
